SPECIFICATION forming Application filed January 4, 1888.

To aZZ whom it may concern.-

Be it known that I, JOHN F. House, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Railroad BailTies and Bait Clamps Combined, of which the following is a specification.

This invention relates to ties for railroadrails and clamp-chairs for securing the rails thereto, and has for its object to provide a durable tie to which the rails are firmly attached without the use of spikes or the ordinary fishplates; and it consists in the peculiar construction and combination of the several parts comprising my improvement, as hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view showing "'my improved tie and rail-clamp as seen complete. Fig. 2 is a vertical section through the tie, showing the plates of which it is constructed and manner of securing them togther. Fig. 3 is a detached perspective view of one of the cone'shaped blocks used in bracing the plates forming the tie. Figs. 4 and 5 are perspective views of the chair-clamps. Fig. 6 is a detached view of one of the wedges used in the clamp for securing the clamp to the tie and the rail to the clamp. Fig. 7 is a plan view showing manner of constructing clamps for the frog.

The first part of my invention relates to the metal tie, which I construct as follows:

A is the lower or bed plate, formed with a raised middle portion, making a hollow space on the under side longitudinally, and in its upper side are made two longitudinal grooves, a a.

B B are flat side plates which set into the grooves a a.

G is the top plate, formed in like shape to the base or bed plate A, but narrower, and provided with grooves (1 cl, similar to thosein plate A. This plate 0 is placed on the top edges of the two side plates, B B, thus forming a box having slanting sides and upper and lower flanges. Near the ends and at the middle part of this box are placed square hollow cones D, and through the upper and lower plates and the cones are placed rivets F,which firmly bind all together. This forms a very strong and durable metal railroad-tie.

The second part of my invention consists of a clamp-chair and wedges for securing the rail part of Letters Patent No. 379,222, dated March 13, 1888.

Serial No. 260,955. (No modelil to the said metal ties, which I construct of malleable iron, as follows:

G is a cast-metal plate provlded with grooved flanges g g on the under side and at the two opposite edges and with like grooved flanges, h h, on the upper side, but transverse to those on the underside.

His a metal wedge having a 'rabbet on one edge, which is used as a key for securing the said clamp-chair to the ties and the rails to the clamp. Two of the groovesg h, it will be observed, are made slightly tapering, for the purpose of having the keys bind tightly in the grooves, and the keys also have a narrow prolongation, k, on their small end, the purpose of which is that said prolongation may be bent to one side when in place on the clamps for securing and prevent their working out.

In Fig. 7 is seen the manner of constructing the clamp-chairs for the frog. They are made with triple clamp, frog-point, and at also with double clamp, ing of the two rails.

By referring to Fig. 1 it will be seen that the abutting ends of the rails meet in the clamp, and that no fish-plates or bolts are rerequired for securing them together. The wedges are made tapering in two sides, so that the rails are crowded and bound down as well as sidewise.

The chair clamps are very firmly wedged to the ties; but the rails I do not clamp so firmly to the chairs, except at the two mid dle chairs, leaving the others with the wedges less tight, in order to give the rails a chance to give to expansive and contraction forces.

Having described my invention, I claim- 1. The improved metal rail-tie, consisting of base-plate A, side plates, B B, top plate, 0, and cone-blocks D, secured by rivets F, constructed and combined substantially as shown and described.

2. The combination, with a metal tie consisting of base-plate A, side plates, B B, top plate, 0, and cone-blocks D, secured together as at K, for the meetas at I, for the heel of the J for the point of the frog,

with rivets F, of the clamp-plates G, having Witnesses:
